How to make
Turn the oven on to 390°F (200 °C). By the time it heats up, you'll have assembled your burek.
Mix all of the ingredients for the filling in a bowl; crumble the feta, grate the cheese, stir well until homogeneous.
Take 3 phyllo pastry sheets, wrap them into a roll and cut them over the filling mixture using scissors.
Arrange the rest of the sheets into a slightly oiled 11 3/4″ (30 cm) diameter tray, while leaving their ends to spill out of the tray and sprinkling with a little oil and lemonade, mixed beforehand, between each sheet using a brush.
Once you've used up the sheets, pour the mixture into the tray, even it out and cover with the ends that spill out (like a lid).
Put the tray in the preheated oven and bake about 30 min. to a golden brown crisp. Take the phyllo pastry out and smear it well with butter on top.
